[6][7][8][9] Raised in Encino, St. John was a member of the Michael Panaieff Children's Ballet Company with Natalie Wood and Stefanie Powers.

"[13] St. John's television debut came in 1948, when she joined the cast of Sandy Dreams, a musical fantasy series for children featuring Richard Beymer.

In December 1949, she played Missie Cratchit in The Christmas Carol, one of the earliest filmed adaptations of Charles Dickens' classic 1843 story.

She had an uncredited role in the film Thunder in the East (1951) and was in episodes of Sky King, Fireside Theatre, and Cavalcade of America.

She played the daughter of Clifton Webb in The Remarkable Mr. Pennypacker and Holiday for Lovers (both 1959), then was put in an adventure movie, The Lost World (1960).

Warner Bros. borrowed St. John for The Roman Spring of Mrs. Stone (1961), then she had a supporting role in Tender Is the Night (1962), for which she beat out Jane Fonda.

She was in a TV movie Fame Is the Name of the Game (1966), and had a supporting role in How I Spent My Summer Vacation (1967), starring future husband Robert Wagner.

[25] The character Tiffany is argumentative, abrasive, loud, and brash when compared to previous Bond girls who were more demure; film scholars have inferred that she is meant to be a stereotypical commentary on American women.

"[27] St. John did the TV movies Saga of Sonora (1973) and Brenda Starr (1976) (playing the title role), and guest-starred on Vega$, The Love Boat, Magnum, P.I., Fantasy Island, and Matt Houston.

She was cast as the princess in Day of the Assassin (1979), but bowed out when her deposit failed to arrive on time; Susana Dosamantes replaced her.

"[29] St. John did the TV movies Two Guys from Muck (1982) and Rooster (1982) and was top-billed in the feature The Concrete Jungle (1982), a woman in prison film in which she played Warden Fletcher.

During 1983–1984, she starred with Dennis Weaver on the short-lived soap opera Emerald Point N.A.S., in which she played Deanna Kinkaid, Thomas Mallory's conniving former sister-in-law.

[33] St. John also developed a handmade Angora sweater business, and became interested in orchid growing, skiing, hiking, river rafting, camping, and gardening.

[34] She is founder of the Aunts Club, a Rancho Mirage-based group of women who contribute at least $1,000 per year to provide financial support for a child.

Her husbands: Between marriages, St. John dated entertainment, sports, and political personalities including Gianni Bulgari, Sammy Cahn, Michael Caine, Oleg Cassini, Barry Coe, Sean Connery, Robert Evans, Glenn Ford, David Frost, Jack Haley Jr., Bill Hudson, Henry Kissinger, Sidney Korshak, Peter Lawford, George Lazenby, Jim Lonborg, Trini López, Tom Mankiewicz, George Montgomery, Joe Namath, Jack Nicholson, Hugh O'Brian, Ogden Mills Phipps, Roman Polanski, Alejandro Rey, Tom Selleck, Frank Sinatra, Robert Vaughn, Giovanni Volpi, Adam West and David L.

Becker, ski instructor Ricky Head, Olympic ski champion Brownie Barnes, plastic surgeon Steven Zax, investment broker Lenny Ross, Chicago businessman Delbert W. Coleman and Brazilian entrepreneur Francisco "Baby" Pignatari.

[10] She has three stepdaughters: In 2007, Wagner and St. John sold the Brentwood ranchette they'd lived on since 1983 for a reported $14 million and relocated full-time to Aspen.

[54][55] Mutual animosity between St. John and her husband's former sister-in-law, actress Lana Wood, extends back to 1971, when Sean Connery was simultaneously involved with both women during the filming of Diamonds Are Forever.

The pair's half-century feud has been highlighted by two well-documented public altercations: one in September 1999, when St. John refused to be photographed with Wood at a Bond girl reunion for Vanity Fair magazine,[56][57] and another in February 2016, when Wood crashed an event honoring St. John in Palm Springs and confronted Wagner over the reopened homicide case of her sister Natalie,[58] who drowned in 1981 while yachting with Wagner off the coast of Santa Catalina Island.
